SPECIFIGATION forming part of Letters Patent No. 628,'749, lated. July 11, 1899;

- Application filed April 20, 1899. Serial No. '713,697. (No model.)

. To all whom it may cancel *nz Be it known that LWILLIAM A. BRADFORD,of Quincy, county of Norfolk, State of Massachusetts, have invented anImprovement in Pipe-VVrenches, of which the following description, inconnection with the acconpanying drawings, is a specification, likeletters on the drawings representng like parts.

This invention relatcs to a novel pipewrench adapted more especially forgrasping and handlingbrass pipe or pipe which is easily scratched andnarred.

My wrench contains a strong woven strap, preferablyof double thickness,the loop made at the doubled end being entered by a strong screw or pincarried by a plate having a hook to engage an eyepiece attached to thehandle of the wrench. The end of the handle is shaped to support thebelt at one side of the pipe embraced by the belt, the belt beingsustained at its outer side near the end of the handle by a supportingstud or roller the free end of the belt being under the control of aclamp.

Figure l shows my wrench as it is being applied to a pipe. 4 Fig. 2shows the wrench engaging a pipe. Fig. 3 is a top view of Fig. 1, andFig. l is a detail of the connection between the strap and the handle.

The handle or handpiece A of the wrench nay be made of any usual orsuitable material, preferably Wood, and its end a will be preferablycnrved to form a seat for one side of the belt f. The inner end of thehandle has applied to it at opposite sides like bracket-s b, each havinga depending ear, as b', in

which is mounted a roller or other stud 17 said stud occupying aposition distant from the lower side of the handle substantially equalto the thickness of the belt c to be described, the brackets beingfirmly confined to the handle by suitable screws ?9 each bracket havingpreferably a projection ?9 to extend above the handle to act as edgeguides for the belt embracing the pipe d. The upper side of the handlehas attached to it by screws c' an eyeplate 0 said eyeplate (see Fig. 4)having an opening 0 said eyeplate covering a hole or recess 0 made inthe top of the handle. The hole in the eyeplate 0 is entered by a hookor projection e, connected with a belt-holder e', having suitable ears 6which receive a detachable screw or rod 6 which is passed through theeye forned by doubling the belt f, preferablyof woven Inaterial, onitself. The belt is stitched or otherwise united one layer with theother and is passed between the end of the handle A and the stud or rollb and thence under a clamp g, composed of a rod having a cam oreccentricand a handle g', said rod having its ends mounted in ears 9united to said handle by suitable screws 9 p In applyin g the wrench toa pipe in position the hook may be disengaged from the eyeplate and thestrap be passed about the pipe and the hook be again engaged with theeyeplate, the handle at such time being somewhat elevated, and the loopin the belt at the end of the handle and enbracing the pipe will be of alength suflicient to enable the pipe when acted upon by turning thehandle to come into a position substantially parallel with and below thebearing-roll ?9 as shown in Fig. 2, where it will be seen that the pipeis wholly embraced by the belt, the latter grasping the pipe withsuficient firrnness to turn said pipe.

This invention is not limited to the exac shape shown for the eyeplateand the hook, and instead I may employ any equivalent device which maybe readily engaged and disengaged when desired, nor is this inventionlimited to the exact form of clamp illustrated.

By making the screw or bolt 6 detachable it is possible to easily removethe strap and completely detach it from the handle.

Having described my invention, what l claim as new, and desire to secureby Letters Patent, is r 1. A pi pe-Wrench consistin g of a handle, aneyepiece on the handle, a belt having a connected hook to detachablyengage said eyepiece, a heavy stud to support said belt near the end ofthe handle, and a movable clamp for engaging said belt beyond said stud.

2. A pipe wrench consisting of a handle, a woven sti-ap folded onitself, a belt-holder ad apted to be hooked or detachably connected withthe said handle, a rod carried by said holder and entering a foldedbight of the strap, ears applied to the end of the handle and supportinga rod to sustain the sti-ap, and a lever pivoted on the handle andhaving a cam to engage the strap at desired times to clamp the same tosaid handle.

3. A. pipe-Wrench consisting of a handle having a pair of brackets atone end provided with depending ears and also With projections, saidprojections constituting edge guides,a hearing-stud supported betweensaid ears, a belt connected at one end with said handle and supported bysaid bearing-stud and guided by said projections, and a clamping devicefor the belt.
